Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reflector for a lighting fixture having a long gutter-shaped reflector main body and end plates fixed to both longitudinal ends thereof.

[Related Art] Reflector plates for lighting fixtures having a long gutter-shaped reflector plate body and end plates fixed to both ends in the longitudinal direction are often used.

The conventional general structure is a form in which each end plate made of a thin steel plate is spot-welded to both ends of the reflector main body, and thereafter, coating is performed. However, there are problems that the electrode traces of spot welding are left on the surface of the reflection plate to impair the appearance, and that a painting process is required after spot welding, so that it takes a long time to complete.

JP-A-58-110902 discloses a reflector for a lighting fixture as shown in FIG. 7 and FIG. This resiliently engages the locking piece 15 on the end plate 2 side with the engaging hole 14 provided in the reflection plate main body 1. In this case, the subsequent coating step can be omitted, which is advantageous in that respect.

[Problems to be Solved by the Invention] The conventional reflectors for lighting fixtures shown in FIGS. 7 and 8 are advantageous in terms of productivity, but the engagement holes 14 are located at prominent locations on the reflector surface. Because it is exposed, it looks bad and damages the commercial value.

SUMMARY OF THE INVENTION An object of the present invention is to provide a reflector for a lighting fixture which does not require welding and has a good appearance.

[Means for Solving the Problems] The reflector for a lighting fixture according to the present invention includes a long gutter-shaped reflector main body, and includes end plates fixed to both longitudinal ends of the reflector main body.

Rising pieces are formed at the edges at both ends in the transverse direction of the reflector plate body. A bent edge is formed at an edge of each of the end plates so as to be folded on an upper surface side of the reflection plate main body.

A socket insertion hole is formed at a position straddling the reflector main body and the bent edges. An end plate side notch corresponding to the socket insertion hole is formed at each bent edge. A notch on the body corresponding to each of the socket insertion holes is formed in the reflector body.

A step is formed at the boundary between the entrance side and the rear side so that the shape of the notch on each end plate side is narrow on the entrance side and wide on the rear side. Folded pieces are formed at opposing sides of the main body side notch.

Each of the bent pieces is bent so as to be folded on the upper surface side of the bent edge via the notch on the end plate side. The base of each bent piece is engaged with the step.

An end of each of the rising pieces of the reflection plate main body is bent so as to hold a part of the end plate.

[Operation] The engagement between the reflector main body and the end plate in the present invention is performed by bending the end of each of the rising pieces of the reflector main body so as to sandwich a part of the end plate. Further, each of the bent pieces in the reflector plate body is bent so as to be folded on the upper surface side of the bent edge through the notch on the end plate side.

The latter engagement is an engagement utilizing a socket insertion hole.
The socket insertion hole is used as an engagement hole. As a result, a large engagement hole is formed at a conspicuous portion on the surface of the reflection plate, but the engagement hole is an original socket insertion hole and is closed by the socket. For this reason, appearance is not spoiled. Since the tip of the bent piece is hidden on the upper surface side of the bent edge of the end plate, it cannot be seen from the outside.

In the present invention, the base of each bent piece is particularly engaged with the step. This step is formed in a notch on the end plate side for forming a socket insertion hole. The base of the bent piece on the reflector body side engages with the step. This engagement acts to prevent the end plate from disengaging from the reflector body. For this purpose, the end plates are firmly engaged.

Example An example of a reflector for a lighting fixture according to the present invention will be described with reference to FIGS. 1 to 6 includes a long gutter-shaped reflector main body 1. An end plate 2 fixed to both ends in the longitudinal direction of the reflector main body 1 is provided. End plate 2
Is made of painted steel plate and is made by pressing a painted steel plate. No painting is necessary after assembling the reflector for lighting equipment.
Rising pieces 21 are formed at the edges at both ends in the lateral direction of the reflector main body 1. A bent edge 9 is formed on the edge of each end plate 2 so as to be folded on the upper surface side of the reflection plate main body 1.

A socket is provided at a position straddling the reflecting plate body 1 and each bent edge 9 (a bent edge 9 attached to one end plate 2 and a bent edge 9 not shown attached to the other end plate 2). An insertion hole 22 is formed. An end plate side notch 10 corresponding to the socket insertion hole 22 is formed in each bent edge 9. A notch 5 on the main body side corresponding to each socket insertion hole 22 is formed in the reflector main body 1. The socket insertion hole 22 is formed by the notch 10 on the end plate side and the notch 5 on the main body side.

A step 23 is formed at the boundary between the entrance side 12 and the rear side 11 such that the shape of each end plate side notch 10 is such that the entrance side 12 is narrow and the rear side 11 is wide. A bent piece 6 is formed at each of opposing sides of the main body side notch 5. Each of the bent portions 6 is bent so as to be folded on the upper surface side of the bent edge 9 via the notch 10 on the end plate side. Connect the base 24 of each bent piece 6 to the step 23
To be engaged.

The end 8 of each rising piece 21 of the reflector main body 1 is bent so as to sandwich a part 13 of the end plate 2.

The engagement between the reflector plate body 1 and the end plate 2
The end portion 8 of the rising piece 21 holds the part 13 of the end plate 2. In addition, the bent piece 6 of the reflector main body 1 sandwiches the notch 10 at the end plate side of the bent edge 9 to make the abdominal muscle.

The mating form of the engagement by the latter bent piece 6 is the socket insertion hole 22 and the end plate side notch 10 therefor. Although it is located in a prominent place on the anti-slope surface, as shown in FIG.
The hole 22 is closed by the socket 3 supporting both ends of the fluorescent lamp 4, and is originally a necessary hole 22. For this reason, it does not correspond to the appearance factor newly derived with the engagement of the end plate 2. In order to use the socket insertion hole 22 as an engagement hole, a new dedicated engagement hole is not required.
The tip of the bent piece 6 is folded back through the socket insertion hole 22 (more precisely, the notch 10 on the end plate side), but the folded portion is on the inner side (upper surface side) of the reflector main body 1 and the end plate 2. , Which cannot be seen from the outside.

By the way, it is not sufficient in terms of engagement strength to simply hold the edge of the socket insertion hole 22 (more precisely, the edge of the notch 10 on the end plate side) at the end with the bent piece 6. By itself, end plate 2
When the strong force in the direction away from the reflector main body 1 is insufficient, the end plate 2 may be partially detached. Therefore, the root 24 of the bent piece 6 is engaged with the step 23 to supplement the engagement strength. Step 23 is notched on the end plate side to form socket insertion hole 22
It is formed in 10. This step 23 is located at the edge of the socket insertion hole 22 and is therefore visible from the outside, but it is located at the socket 3, so that the step 23
Unless you make 23 too large, it will not be noticeable or unsightly.

Reference numeral 7 denotes a hole formed in the bending piece 6 on a line to be bent. The hole 7 corresponds to the inlet side 12 in the notch 10 on the end plate side. One end of the hole 7 serves as the root 24 that engages with the step 23. The hole 7 corresponds to the inlet side 12, and the width of the former is slightly larger than that of the former.
24 contacts the step 23.

[Effects of the Invention] As described above, according to the present invention, socket insertion holes are formed at positions straddling the reflecting plate main body and each bent edge of each end plate, and the socket insertion holes are formed at each bent edge. Form the notch corresponding to the end plate side, form the notch on the main body side corresponding to each socket insertion hole in the reflector plate body, make the shape of each notch side notch so that the entrance side is narrow and the back side is wide A step is formed at the boundary between the entrance side and the back side, and a bent side is formed at each opposite side of the main body side notch, and each bent side is formed through the end plate side notch. The main feature is to bend so as to be folded on the upper surface side of the bent edge, and to engage the root of each bent side with the step.

According to this, a reflector for a lighting fixture which does not require welding and has a good appearance in appearance can be obtained. In addition, the engagement strength of the end plate with the reflector main body is large, and there is no fear that the end plate comes off.
